Micro-IMU Module
Product Model:
MSI310F
Product Features
● Miniaturization
● Low power consumption
● High cost performance
● Full Temperature Compensation
Product Introduction
The MSI310F micro inertial measurement unit is a versatile, miniaturized inertial component that integrates three-axis gyroscopes and three-axis accelerometers. By applying temperature compensation to the zero bias and scale factor of each axis, its measurement accuracy is significantly enhanced.
